Title: Improvements in or relating to travelling wave amplifiers
Inventor: CHICK MORLEY THOMAS GEORGE
IPC: H01J23/06
Filed: 1956-05-31
Abstract: 810,873. Travelling wave tubes. STANDARD TELEPHONES & CABLES Ltd. May 31,1956 No. 16823/56. Class 39(1). In a travelling wave amplifier of the helix type undesiried direct coupling between the input and output feeders 7, 8 occurs due to the tunnel formed by a support and/or screening member, e.g. the focusing solenoid 2 or, if of metal, the tube envelope, serving as a hollow pipe waveguide, is prevented by at least one thick collar 12, 13 of non magnetic lossy material surrounding and spaced from the helix 4 a sufficient distance so as not to interfere with the slow wave mode propagating on the helix 4 and extending radially almost completely or completely to the tunnel wall and being of such length (or of such total length in the case of a pluraility of collars) as to suppress the direct coupling between the feeders 7, 8. There are preferably two collars 12, 13 one adjacent each wave guide feeder 7, 8. The lossy collars are of carbon loaded ceramic or of conducting rubber. Brass end collars 10, 11 support and centralise the solenoid. Further solenoids (not shown) surround the tube ends. The tube envelope shown is of glass but may as indicated above be of metal. The invention is a development of an experimental arrangement, not according to the invention, in which, instead of lossy collars a brass tube closely surrounds the travelling wave tube and is held in the brass end collars 10, 11. The loss of the brass tube could be increased by coating it on the inside with lossy material. Prior art devices are referred to such as (a) the preferntial fast mode suppressor of British Patent 660,793, which may be a thick collar of lossy material surrounding the helix and surrounded by a solenoid and (b) loss material such as a coating 9 on the helix support rods or a collar surrounding and touching or very closely spaced from the helix so as to be capacitively coupled thereto.
